maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e

Recently While importing one Maven project into Eclipse(Juno, m2e plug-ins is already installed in Eclipse). I was getting one error in project : maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e


Reason: Eclipse m2e does not support execution, by copying the below code in the build tag resolve the issue.

Example:

<build>

<COPY_CODE_HERE>

</build>

Code :

<pluginManagement>

<plugins>

<!--This plugin's configuration is used to store Eclipse m2e settings

only. It has no influence on the Maven build itself. -->

<plugin>

<groupId>org.eclipse.m2e</groupId>

<artifactId>lifecycle-mapping</artifactId>

<version>1.0.0</version>

<configuration>

<lifecycleMappingMetadata>

<pluginExecutions>

<pluginExecution>

<pluginExecutionFilter>

<groupId>

org.apache.maven.plugins

</groupId>

<artifactId>

maven-antrun-plugin

</artifactId>

<versionRange>

1.7

</versionRange>

<goals>

<goal>run</goal>

</goals>

</pluginExecutionFilter>

<action>

<ignore></ignore>

</action>

</pluginExecution>

</pluginExecutions>

</lifecycleMappingMetadata>

</configuration>

</plugin>

</plugins>

</pluginManagement>

Save the project and it will resolve the issue, if not then Right click on your project and update Maven(Maven → Update Project... ).
